Using Adaptive Cruise Controls on Hills
and When Towing a Trailer
How well Adaptive Cruise Control works on hills and
while a trailer is being towed depends on your vehicle
speed, vehicle load, traffic conditions, and the steepness
of the hills. It might not detect a vehicle in your lane while
driving on hills. While going up steep hills, you might want
to use the accelerator pedal to maintain your vehicle
speed. While going downhill and towing a trailer, you
might want to brake to keep your vehicle speed down.
Applying the brake disengages the system. You may
choose not to use Adaptive Cruise Control on steep
hills when towing a trailer.
Disengaging Adaptive Cruise Control
Apply the brake pedal or move the Adaptive Cruise
Control switch to off, to disengage the system. Adaptive
Cruise Control information does not appear on the
HUD while the system is not engaged.
Erasing Set Speed Memory
The set speed memory is erased when the Adaptive
Cruise Control switch or the ignition is turned off.
Other Messages
There are three messages that may appear on the DIC.
They are SERVICE RADAR CRUISE, RADAR CRUISE
NOT READY and CLEAN RADAR. These messages will
appear to indicate a problem with the Adaptive Cruise
Control. See DIC Warnings and Messages on page 3-79
for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If this happens, turn off the engine and clean the emblem/
lens, located in the center of the front outside grille.
Do not use Adaptive Cruise Control in icy conditions,
or when visibility is low, such as in fog, rain or snow.
To clean the emblem/lens, wipe the surface with a soft
cloth. After cleaning the emblem/lens, engage the
Adaptive Cruise Control. If you are unable to do so,
see your dealer/retailer.
